- check releaseHelper support when selecting bindless mode, if not
disabled, prefer bindless mode in L0 API
- bindless mode can be forced with DebugVariable: UseBindlessMode

Added getDefaultDeviceHierarchy call that describes default device
hierarchy for a gfx core. Refactored L0 and OCL paths to use this
value by default and override this value when user sets
ZE_FLAT_DEVICE_HIERARCHY environment variable or
ReturnSubDevicesAsApiDevices debug key.
Updated ReturnSubDevicesAsApiDevices to force COMPOSITE device hierarchy
when set to 0.

- For calculating number of threads per workgroup, for SIMD 1, return
local work size (each software thread should be mapped into a whole hardware
thread).
- Correct logic of calculating space for per thread data for SIMD 1.
- Minor: unit tests refactor.
- Corrected naming.

So far, there is a separate page allocated for each kernel's ISA within
`KernelImmutableData::initialize()`. Apparently the ISA blocks are often
much smaller than a 64k page, which leads to poor memory utilization and
was even observed to cause the device OOM error if a single module has
several keys.
Improve the situation by reusing the parent allocation (owned by the
module instance) for modules, which kernel ISAs can fit together within
a single 64k page. This improves the memory utilization on a single
module level.

For all of the devices, preferredPlatformName is initialized with
nullptr by default and platform name will be initialized to driver's default
platform name, at the moment this is "Intel(R) OpenCL Graphics".
When Platform is initialized and preferredPlatformName is not nullptr then
Platform name will be set to the value stored in preferredPlatformName.
Add ENABLE_LEGACY_PLATFORM_NAME AIL enum related to added functionality.
Move PlatformInfo to NEO namespace.
